Screamer is a combination password (actually, pass key) protection program, screen saver, and joke program. When the program is activated, it freezes the computer until someone presses the correct code key or key combination (such as Alt-F1). If anyone presses any key other than the correct code key, the program screams "Help! Don't touch me! Unauthorized use of this computer. Help!" through the computer's speaker. No extra hardware is required to use this program.
